LEVI E. LANE AND GEORGE HILLIARD, OF LYONS, NEV YORK.

WAGON-BRAKE.

SPECIFICATION forming part of Letters Patent No. 400,228, dated March26, 1889.

Application led November 17, 1888. Serial No. 291,169. (No model.)

To all whom, it may concern:

Be it known that we, LEVI E. LANE and GEORGE HILLIARD, residents ofLyons, in the county of Vayne and State of New York, have inventedcertain new and useful Improvements in Automatic lagon-Brakes; and we dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit pertains to make and use the same.

This invention relates to brakes -for vehicles; and it consists incertain improvements in the construction of the saine, as hereinafterdescribed and claimed.

In the accompanying drawings, Figure l is a plan view of therunning-gear of a wagon provided with our improved brake. Fig. 2 is aside view of the same. Fig. 3 shows in front view the brake-bar and thearm supporting it. Fig. 4 is a view of the brake-shoe.

A designates the tongue of the wagon, the

point of which is provided with a tube or sleeve, d, which is looselyplaced thereon,the said tongue being reduced at the point and provided'with a shoulder to limit the rearward movement of the sleeve, which isprovided with a loop for connection with the Vneck-yoke.

To the sleeve d is secured one end of a rod, 7), which ext-ends rearwardunder the tongue, and is connected at its rear end with a yoke, d, whichis formed of a bent rod, as shown. To retain the rod and the said yokein place, they are loosely secured to the tongue and to the axle B bymeans of staples c.

C indicates the reach, which extends rearward from the front axle, B,and the bolster to the rear axle, D. In a slot in the said yreach nearits forward end is pivoted a short lever, f, the lower end of which isformed to hook on the rear part of the yoke (l, which is formed on apart of a circle, as shown, so that it will slide in the hook on lever fwhen the front axle, B, is turned in either direction. Another shortlever, g, is pivoted to the reach some distancerearward from the leverf, and a connecting-rod, 7L, connect-s the upper end of lever f with theupper end of lever g, the rear end of said rod being slotted andperforated for the purpose of adjusting the rod in length between thetwo levers, as may be found necessary. The upper end of the lever g isslotted to allow amovement of the rod h, the rear end of which riseswhen the brake is closed.

To the lower end of the lever g is secured the rear end of aconnecting-rod, lo, the forward end of said rod being bifurcated andconnected with the brake-bar m, which carries the brake-shoes n, whichare in position to be closed against the hind wheels, E, of the wagon,as shown. to the reach C and extend at right angles therefrom, as shown,the extremities of said arms being` united and bent downward andforward, so that they form supports for the brake-rod m at points nearthe shoes n. The brake-rod m is further supported by the yoke r, whichis fastened thereto and which is also att-ached to the reach C, and hasits movement forward or rearward as the brake is operated. The shoes nare pivot-ally connected with the brake-bar, and are provided withsprings c, which serve to retain them in position to close against thewheels. In backing the vehicle the shoes are automatically turned upwardon their pivots by the rotation of the wheels, the springs allowing theshoes to turn on the brake-bar, and thus only a minimum degree offrictional resistance is offered by the brake-blocks to the wheels.

As will be seen, the brake-rod l1n is supported in position below theplane of the axle of the rear wheels, so that when the brake is closedagainst said wheels in backing the team the rearward revolution ot saidwheels is not prevented by the binding of the shoes n against them, butthe revolution of said wheels in the opposite direction, as in theforward movement of the vehicle, will be immediately stopped by theclosing of the shoes against them.

The bolt s, by which the whiiletree is secured to the tongue, is passedthrough a slot, fu, in the hammer-strap w and through a slot in thetongue, and the lower end of the bolt is connected with the rod l?, sothat when the vehicle is drawn forward the rod b is drawn, and throughthe rearward connections of said rod the brake is moved from the wheelsE.

The closing of the brake against the wheels Two arms, p, are fastened lis el'eeted by simply eheeking or backing the team, whereby the sleeve ais pushed hack, thus moving rearward the rod l) and operati ing thepivotal levers and connecting-rods,

Ironi and having the supporting-yokes slidi ing on the reach, and thebar 7"', connecting the lower end of the lever g to the brake-bar,substantially as described.

2. In an autolnatie vehicle-brake apparatus, the brake-bar, thebrakeshoes pivoted thereon and adapted to turn axially, and theinverted-V-shaped springs fr, each having one end secured to the pivotalpart of the brakebar and the other end attaehed to one of thebrake-shoes, for the purpose set forth, sul)- stantially as described.

ln testimony whereof We have signed this speeieation in the presenee ot'two subscribing witnesses.
